there is no communication among unknown parties. someone somewhere gives you a key.

http://btcbase.org/log/2017-11-08#1734517 << not quite. for encryption, if I get your modulus, and you actually want
to read my messages, I can generate a public exponent between M/2 and (say) 3M/4, and attach it
to
the message in plaintext.
diana_coman: that being said, I can't quite see it being any *worse*
than
this affair with fixed size AND fixed
top bits
☟︎ diana_coman: apeloyee, my first
thought went
that way but
then on one hand
this just makes
the interval larger basically and on
the other hand I have no idea how
to even evaluate
the compromise (i.e. how large interval is large enough anyway, leaving aside
that
the how big is big enough for p and q is not
that
terribly clear either -at least not
to me); in other words I can see it as an improvement but I can't actually evaluate it clearly
apeloyee: diana_coman: if keeping
the minimum of 2^2047 for primes, you can, for example, generate primes between 2^2047 and 2^2049, and start over if
the modulus is unacceptable. not sure what minimum for p and q makes sense.

to B bytes, with B given on commandline and stackframed on warmup.
a111: Logged on 2017-11-13 19:36 asciilifeform: and rewrite
the parser per se in scheme ( have it be present as commented bytecode constant )
spyked:
http://btcbase.org/log/2017-11-13#1737264 <-- strings are (lisp) lists-of-characters. which, as it is, unfortunately makes parsing and evaluating builtin functions (e.g. cons, car, cdr) a pain in
the ass. can be structured cleanly
though. also,
this makes it not a simple matter of find+replace in shithub scheme.adb.
☝︎☟︎ diana_coman: apeloyee, if I understand
that correctly basically
the only way
to plug
that leak would be
to give up on diddling p and q, including setting size; which would mean just get random pairs of primes until
their product fits
the desired number of bits for
the key; obv
this lands into
the
trouble of having one of
them
too small
☟︎ a111: Logged on 2017-11-13 19:36 asciilifeform: and get rid of
the pointers.
apeloyee: assuming M is a modulus of a useful RSA key,
this will work
a111: Logged on 2017-11-08 22:03 asciilifeform: not knowing
the e has exactly same effect as not knowing half of
the n.
apeloyee: if M is say, 1.999999 * 2^2047,
then ~20 first bits of p and q are known
☟︎ apeloyee: can't see how
to plug it completely
though
apeloyee: if "no leaks on principle",
this needs
to be dealt with
apeloyee: if
the modulus is M,
then p,q>M/2^2048 (because p,q<2^2048)
☟︎ apeloyee: fwiw I just realized
that
this ^ leaks a little via
the modulus
diana_coman:
http://btcbase.org/log/2017-11-14#1737414 <- confirmed; I do NOT use any nextprime or other "rng"-parts from gpg; current rsatron prototype simply grabs nbits from fg, flips
the 2
top bits and 1 bottom bit as per previous discussion and
then checks if result is prime; if prime
then keep, otherwise discard and
try again; no "add 2 until prime" or other such
thing

☟︎ mircea_popescu: i get odd viral influenzas in
the first months of mingling with
the whores of a new land also.
mircea_popescu: very important NOT
to use any kind of nextprime, as it
turns out .
mircea_popescu: asciilifeform no, because see, if you don't use nextprime you lack
the "nop bridge" so
to speak. rolling number 6 does not
take you
to 7.
to get 7 you need a natural 7, and
this is equiprobable
to rolling a natural 2^74207281-1 on
the space of (0,2^74207281-1).

the bit-banging of inputs, fired off a run late last week
that is *still hashing*
mircea_popescu: it's still an unreturned function "what other bits are lost what other places". so
this 4090 still an upper bound.
mircea_popescu: clarity is more valuable
than a nearer asimptote, in many contexts.

there's nothing in principle wrong with
the 2045 bit primes, except, of couyrse,
the lying about it.

mircea_popescu: as you'll reject
the primes and end up with
the same 2045 bits of entropy
